Well I feel stupid now. I never set the brakes, I just hold the B key except for this one specific time. I gotta say though, thanks for all the help guys, you gave me info that I will most likely need as I further test my rover. LordFjord - Those are the wheels I'm using. I remember problems with placing the wheels onto the I-beams I have for the chassis. Maybe we could turn this thread into a general rover help thread or something? I started off trying to place the I-beams, then the wheels, then figured out its easier to do one I-beam, place the wheel, go to 2x symmetry, place it, then alt-click and place the other two wheels...so much easier. Any other tips you guys have for rovers? Mine is more for landing, hitting F5 and driving around trying to go off jumps and crashing, F9 and repeat. What do you guys do to make your rovers more valuable to a mission rather than just a fun toy?
